The only thing is if you are going to upgrade to Callpilot I would call your Vendor today and place the order. The promotion that Nortel currently offers will end on Monday for most vendors. At that point the cost will almost triple for Callpilot. There are some nice features that CP offers, Desktop messaging being one of them. CP does not offer forms or support PMS, but you really don't use those features. The other thing is Nortel is taking back all of the MM hardware when you upgrade so some of the parts may be difficult to find in the future. As far as CP being better or worse than MM I think they both have good points. CP now supports more then 1 MWI DN, like release 13 of MM. The menus are a little easier to build and you don't have to jump back and forth between menu service, thru dial, and TOD, but recording the prompts takes a few times to get used to. The mailboxes are built and some maint can be done thru a GUI interface that you can put on your LAN so if you can get into the network, or any PC on the network, you launch IE then you can build and maintain Mailboxes, this was done via the modem with MM and the A/B switch. You can also RAS into the server and launch IE to make any changes. The best part is the desktop messaging and this is something that MM doesn't offer.
